To. whom t may concern;

Be it known that I, Jol-IN VITTEMANN, a citizen of the United States, and a resident of the city of Milwaukee, county of Milwaukee, and State of IVisconsin, have invented a new and Improved Detachable Shade-Holding Bracket; and I do declare the following Ito be a full, clear, and exact description thereof, such as will enable persons skilled in the art to which the invention pertains, to make and use the'same, reference beinghadV to the accompanying drawings for a disclosure'of one construction in whi'clithe invention has been embodied'.

Myv invention relates tti-brackets for supporting` the rollers of window shades.

The inven tionV resides in a rbracket designed to beatt'aclied to the upper sliding sasli'ef a window, in such position that the upper 'i sash with its shade supporting atf ynentsv4 may be loweredwithout disturbing theishade attachments, so as to admit vehtilatingcurrents of`air to pass through the open space above the topof lthe lowered sash, and thus secure a better hygienic condition in the room from which the window .Qpens A.

-.reason of the fact that the shade roller is su aported byand is moved withthe sash, the sliade may be drawn and privacy Vof the renin be preserved. ADrdinari-ly, this/iis a result whichl cannot be attained .without Yliability ofl damage to the `shade, as it is Vquite usual to Asupport the shade roller in bracketswwhich are fixed to the front or to the sides ofthe window casing, and when draw-n, the shade issubject to agitation by the Ventilating currents of air, with consevquent'dal-mage tothe shade, the latter s ometimes being torn .f1/#omits engagement with the shade. roller by violent gusts of wind, .andthe privacy of the room entirely destroyied until the matter can' be remedied. Again, the desire to protect the shade from damage under such yconditions necessitates ,the shade being fully raised and wound upon the roller, and this again creates that undesirable publicity which the lproper use 'of 1the shade is vintended .to obviate.

VMy invention embodies afflat stirrup or loop designed to be .attached to the stiles of .the-upper sash, and to lie such proximity thereto ythat will not interfere with the raising or'lowering of either sash Vfor the .purpose of cleaning the window panes.

The peculiar form of bracket which I use for supporting the shade roller is easily connected with tliefstirrup or loop in a manner to firmly support the shade'reller when the latter has been placed in position, and is detachable from its connection with the stirrup or loop with equal facility, whenever it may be desirableto remove the shade and its supporting` brackets for any purpose.

' The stirrup or loop when secured to the stiles of ,the sash as before referred to, provides an opening or space into which anangularly formed foot on the shade roller rsupporting bracket may be entered and retained securely against the possibility of accidental dis'placement.r The journal at one end of the shade roller, and the 'shaft at the other end, to which the spring for rotating the shade roller is attached,v are received in bearings formed in the` brackets, and when in position'the shade roller acts to perfect the engagement of the foot Von each bracket frictionally with its respective stirrup or loop, by exertinga lateral pressure uponV the brackets, but while the pressure L.

thus exerted contributes to theeffective locking of the parts intheir relative positions, suoli pressure does not'in any degree retard ther free rotationiof'the roller when desired to raise or lower ythe shade. l i Each of the brackets is provided with a widened stop formed' as a part thereof and designed to' contactwith the meeting rail of the lower sash, and so prevent "damage to .the latter, should the lower sash be' raised so high as to contact with the brackets.`

' In 'the drawings which formr part of this specification,

' Figure l is a view in elevation showing an Iordinary window frame, looking from the interior of the room, and showing the manner in which my improved detachable shade holding bracket may be used.

Fig. 2 is Van enlarged plan view, showing the top rails of vboth sashes, and my improved bracket in position at one side of the window casing, the latter being shown in section, and showing also the relative arrangement of `the stirrup or loop 'and' `the bracket at the other end ofthe shade roller. Fig. 3 'is Ia view in ,elevation ofthe sti'iiru'p or loop. Fig. i is a view in `elevation of the bracket.

The general arrangement o f the parts .is

shown in Fig. l of the drawings. In this view, the upper sash to which the attachments are applied, is shown as partly lowered so as to provide a Ventilating opening,

through which currents of air, no matter how strong, may pass without vibration of the fabric of which the shade is composed. In this view, the shade is shown as but partially drawn, but it is obvious that the shade may be completely drawn so as to secure privacy in a room, and still maintain the provisions for ventilation.

In Fig. 2 the bead A and the parting strip B, set in grooves in the casing C of the window frame, serve to guide the upper sash l), and between the strip B and the stop E, fixed to the casing, the lower sash F will be guided, all as usual in similar building constructions. The sashes are thickened at their meeting rails, so that when the chamfered or beveled portions d and f of the rails are brought together, the space in the line of the parting strips will be closed.

To each of the stiles of thev upper sash D, and at or near the top thereof, I attach the stirrup or loop I-I, shown in Fig. 3, and in cross section at the right in Fig. 2. In the latter view, the central or engaging portion of the stirrup or loopis offset and inclined as at 7i., with respect to the plane in which the. stirrup or loop lies when attached to the sash, the angle of such inclination diverging from the sash toward the middle line thereof, whereby there is formed a pocket having a restricted opening adjacent the vertical edges of the sash. Each stirrup or loop is set a measured distance from the vedge of the sash so as to provide a clearance for a purpose to be presently described. As shown, the extremities of the stirrup or loop are provided with perforations .through which are passed the means for securing the part to the sash.

A bracket I is provided with a foot c', formed integrally therewith, and bent to an angle which is slightly acute, which foot will be of a length not exceeding the width of the clearance hereinbefore referred to. The foot of the bracket is slipped laterally into the restricted opening and seated in the pocket, before described, and is thus held in position to receive and support the shade roller. In the matter of length, the brackets will extend sufficiently beyond the vertical plane in which the lower sash may be moved, to permit the said lower sash to be raised without contact with the shade which depends from the roller journaled in the ends of the brackets. The relative position of the roller is indicated in Fig. 2. One of the brackets will be provided with a circular bore for the reception of the journal or pin in one end of the shade roller.V Such bore is indicated by full lines in Fig. il. The other bracket of the pair will be provided with a slot or angular opening for the reception ofthe end of the spring shaft at the other end of the shade roller, whereby the said shaft will be held against rotatien, during the rotation of the shade roller under the pressure exerted by the spring connecting the shaft and roller, as is well known. The approximate dimensions of such slot are indicated by dotted lines, Fig. 4C. A widened stop i, formed integrally with the bracket at the lower edge thereof, and standing at a right angle thereto, is adapted to project over the lower sash so as to contact with the meeting rail of the latter when such sash is raised, and thus prevent damage to such rail by reason of the broadened bearing surface thus provided.

In assembling the parts of the invention, the foot on the bracket is inserted in the stirrup or loop, as previously described, and the pintles of the shade roller are inserted in the respective openings in the brackets, by springing such brackets apart in a slight degree, and as indicated by the dotted lines in Fig. 2. The inherent resiliency of the construction is such that the frictional engagement between the stirrup or loop and the foot of the bracket will hold the parts in their assembled posit-ions and against accidental displacement, and the shade roller, acting as a distance piece between the Vbrackets will serve to make the locking engagement of the parts more effective.

From what has been described as to the manner of assembling the parts, it isobvious that disassembling or detachment of the parts may be effected with equal facility. Then detached, both sash may be moved the full length of the window frame, without interference by the stirrups or loops, which latter lie entirely beyondY the plane of movement of the bevelled or chamfered portion of the meeting rail of the lower sash, and consequently no damage to such sash will be caused by the but slightly projecting stirrups or loops when the sash are shifted from top to bottom, as `will be desirable in clean'- ing the window panes, or for other purposes. By reason of the angular engagement of the foot of the bracket with a st-irrup or loop, the bracket cannot be released from. such engagement until after thebracket has been moved or turnedon its heel 2, so as to bring the foot into parallelism with the plane of the sash. It will be clear that when the brackets are separated by the placing of the shade roller inposition, there can be no such turning movement of the bracket, and that any bodily outward movement thereof is prevented.

My invention possesses several very convenient features, and may be produced, by reason of the simplicity of its construction, at a very low cost. i

Having thus describedmy invention, what I claim and desire to secure by Letters Patent of the United States, is:

l. A Window shade fixture comprising a bracket holding stirrup or loop for attachment to a Window sash, such stirrup or loop having the bracket sustaining part thereof disposed at an angle which is inclined With respect to the plane of the sash, and a shade roller supporting bracket provided with a correspondingly forward angularly eXtending foot adapted for engagement with the stirrup or loop, whereby when engagement of the angular faces of the foot of the bracket and the sustaining stirrup is effected, the bracket is held against displacement.

i2. )i Ywindow shade supporting fixture comprising a stirrup or loop for attachment to the front side of' a Window sash, such stirrup or loop having a bracket engaging portion offset from the plane of' the sash, and a roller-supporting bracket provided with an angularly extending foot adapted to be loosely inserted in the engaging portion of the stirrup or loop, a like fixture at the other side of the sash, and a shade roller extending between and supported by the said brackets and adapted tol spread them apart to effect locking engagement of the feet on the brackets with the stirrngs.

3. detachable Window shade fixture comprisino' a stirrup or loop for attachment to a Window sash, such stirrup or loop having a bracket-sustaining portion offset and inclined from the plane of the sash, a rollersupporting bracket having an inclined foot adapted to be loosely inserted in the sustaining portion of the stirrup o-r loop, and means for moving the bracket to effect a loc-king engagement of the said inclined parts to prevent accidental displacement of the bracket While a shade is in position.

4l. A shade holding fixture for Windows With sliding sash, comprising a stirrup or loop for attachment to the front side of the upper sash, and adapted to lie Wholly outside of the plane of movement of the lower sash, a roller-supporting bracket havin an angularly extending foot thereon for frictionally engaging the stirrup or loop to retain the bracket in position, and having a Wide bearing stop on one edge thereof to arrest relative movement of' the sash past each other, the bracket being slidably demountable from the stirrup to permit the sash to be moved the full length of the Window frame, Without contact with the said stirrup.

In testimony whereof, l have signed my name at Milwaukee, this '7th daf,7 of February, 1920.
